In the wake of the deadly bridge collapse in Washington, interest has increased in the current condition and safety of Pennsylvania’s bridges. With the average age of bridges on the state system well over 50, PennDOT must evaluate the numerous bridges and consider the needs and costs of the state infrastructure. According the Pennsylvania Department of Transportation, Allegheny County has 2,247 bridges yet many of them are categorized as structurally deficient or functionally obsolete.
